Home -> Community -> Mailing Lists -> Oracle-L -> Re:Compressing Export Dumps/WinZip
Patrice,
Yes, that's right. On our Tru64 Unix platforms, I was amazed to find that even though I knew the export dump files to be binary files and (what I assumed to be) not only Oracle-extent-compressed, but binary-data-compressed.......that in using gzip/gunzip we were achieving compression percentages of up to 50% and even more.

I don't know whether this is a tangent, but I notice that on the windows platform, "compressed" exports can still get 85% compression when zipping them with WinZip.
Obviously Oracle "compressed=y" doesn't mean "compress the export file", it just means that it places all the segments contiguously in the export file.
Right?
